5. Post-Doctoral Appointment / Special Experience

1990-1997 Senior Physicist, Loma Linda University Medical Center Proton Therapy Facility

Following completion of my Ph.D., in lieu of a Post-Doc, I went to Loma Linda

University Medical Center as a Senior Physicist to develop, test, calibrate, and

commission the world’s first hospital based proton radiation therapy center using the

same accelerator that I used for my Ph.D. thesis research at Fermi National Laboratory.

Calibration of the proton therapy center required adapting existing radiation dosimetry

protocols and recommendations to proton beam therapy. Furthermore, my

responsibilities encompassed designing and developing improved radiation treatment

beam delivery systems for use in the proton therapy facility.
